National Oil and Hazardous Substances Pollution Contingency Plan
National Priorities List
AGENCY: Environmental Protection Agency.
ACTION: Notice of intent to delete the Vestal Water Supply Well 4-2
Superfund Site from the National Priorities List: request for comments.
-----------------------------------------------------------------------
SUMMARY: The Environmental Protection Agency (EPA) Region II announces
its intent to delete the Vestal Water Supply Well 4-2 (Vestal 4-2) Site
from the National Priorities List (NPL) and requests public comment on
this action. The NPL constitutes appendix B of 40 CFR part 300, which
is the National Oil and Hazardous Substances Pollution Contingency Plan

(CERCLA), as amended. EPA and the State of New York have determined
that no further action is appropriate at the Vestal 4-2 Site under
CERCLA. Moreover, EPA and the State have determined that the activities
conducted at the Vestal 4-2 Site are protective of public health and
the environment.
DATES: Comments concerning the deletion of the Vestal 4-2 Site from the
NPL may be submitted on or before September 10, 1999.
ADDRESSES: Comments may be mailed to: Lorenzo Thantu, Remedial Project
Manager, U.S. Environmental Protection Agency, Region II, 290 Broadway,

I. Introduction
EPA Region II announces its intent to delete the Vestal Water
Supply Well 4-2 Site (Site), located in Vestal, Broome County, New
York, from the National Priorities List (NPL) and requests public
comment on this action. The NPL constitutes appendix B to the National
Oil and Hazardous Substances Pollution Contingency Plan (NCP), which
EPA promulgated pursuant to section 105 of the Comprehensive
Environmental Response, Compensation, and Liability Act (CERCLA). EPA
identifies sites that appear to present a significant risk to public
health, welfare, or the environment and maintains the NPL as the list
of those sites. Sites on the NPL may be the subject of remedial actions
financed by the Hazardous Substances Superfund Response Trust Fund
(Fund). Pursuant to Sec. 300.425(e)(3) of the NCP, any site deleted
from the NPL remains eligible for Fund-financed remedial actions, if
conditions at such sites warrant such action.
The Vestal 4-2 Site is located on the west side of Prentice Road in
the Town of Vestal, Broome County, New York. The Town of Vestal is
about five miles southwest of Binghamton. Well 4-2 is about 1,000 feet
south of the Susquehanna River and is one of four water supply wells in
Water District Number 4 of the Town of Vestal.
EPA will accept comments concerning the Vestal 4-2 Site for thirty
days after publication of this document in the Federal Register.
II. NPL Deletion Criteria
Section 300.425(e)(1) (i)-(iii) of the NCP provides that sites may
be deleted from the NPL where no further response is appropriate. In
making this determination, EPA, in consultation with the State of New
York, considers whether any of the following criteria has been met:
(i) Responsible or other parties have implemented all appropriate
response actions required; or,
(ii) All appropriate Fund-financed responses under CERCLA have been
implemented and no further cleanup by responsible parties is
appropriate; or,
(iii) The remedial investigation has shown that the release poses
no significant threat to human health or the environment and,
therefore, taking remedial measures is not appropriate.
III. Deletion Procedures
The following procedures were used for the intended deletion of the
Site:
(1) Two Reports, issued in 1980 and 1981, determined that the
source of Vestal 4-2 contamination was the Monarch Chemical, Inc.
facility.
(2) In 1993, the Town of Vestal had a former dry well and
surrounding soils removed from the Monarch facility.
(3) In 1997, groundwater sampling confirmed the cleanup of the
aquifer.
(4) The New York State Department of Environmental Conservation
(NYSDEC) concurred with the deletion in a letter dated September 29,
1998.
(5) EPA Region II has recommended deletion and has prepared the
relevant documents. EPA has also made all relevant documents available
in the Regional office and local Vestal 4-2 Site information
repositories.
(6) Concurrent with this national Notice of Intent to Delete, a
notice has been published in a local newspaper and has been distributed
to appropriate Federal, State and local officials and other interested
parties announcing a thirty-day public comment period on the deletion.
Comments received during the comment period will be evaluated
before any final decision is made. If necessary, EPA Region II will
prepare a Responsiveness Summary which will address any significant
comments received during the public comment period. A deletion occurs
when the EPA Regional Administrator places a final Notice of Deletion
in the Federal Register.
IV. Basis for Intended Site Deletion
In February 1980, Vestal Water Supply Well 4-2 was found to be
contaminated with trichloroethene, 1,1,1-trichloroethane and
tetrachloroethene. The Vestal 4-2 Site was listed on the NPL on
September 1, 1983.
An October 1980 report entitled, ``Hydrogeologic Investigation of
Organic Contamination at Monarch Chemicals, Inc.,'' and an April 7,
1981 draft report entitled, ``Hydrologic Study of a Portion of the
Susquehanna River Valley in the Town of Vestal, Broome County, New York
with Emphasis on Chemical Contamination of the Aquifer,'' together
delineated the nature and extent of the suspected contamination at the
Vestal 4-2 Site and documented that the Monarch facility was the source
of contamination of Well 4-2.
The Monarch Chemicals is located approximately 200 feet south and
hydraulically upgradient of Well 4-2. Monarch Chemicals began
operations around 1970, repackaging chemicals including 1,1,1-
trichloroethane, trichloroethene and other chlorinated solvents as part
of a bulk chemical handling operation.
In April 1983, the ``Town of Vestal Water District No. 4,
Groundwater Exploration'' report was released. The report found that
the contamination in the vicinity of Well 4-2 was a localized
condition. The report also indicated that although Monarch Chemicals
vacated its premises in the Fall of 1982, the continued presence of
contaminants in Well 4-2 indicated that the Monarch facility remained
contaminated. The report recommended that Well 4-2 should continue to
pump to waste unless another remedial action were taken to remove the
contamination. These conclusions mapped out the remedial alternatives
which were later incorporated in the New York State Enforcement Action,
also known as the Settlement Agreements.
In 1985, the New York State Department of Law, Attorney General's
Office along with the Town of Vestal and the Vestal Water Districts No.
3, 4 and 6 signed two Settlement Agreements with the responsible
parties at the Site.
In September 1988, as a result of the Settlement Agreements, an air
stripper and additional carbon filtration were installed at Well 4-2.
The air stripping system reduced contaminant levels in groundwater to
below detection limits.
On December 14, 1993, approximately 26 cubic yards (42 tons) of
material were excavated including the former dry well and surrounding
soils from the Monarch Chemicals facility.
In order to determine if groundwater contaminants had attenuated
and if it were appropriate to begin the NPL delisting process for the
Site, EPA sampled the groundwater in the vicinity of the Vestal 4-2
Site on May 8, 1997, June 11, 1997 and September 10, 1997. The results
of the sampling showed that groundwater contamination in the vicinity
of the former Monarch
[[Page 43643]]
Chemicals dry well had decreased, such that it was at or approaching
drinking water standards.
EPA's 1997 sampling data are consistent with the Town's monthly
monitoring results for samples collected prior to the air stripper.
Therefore, the primary pathways associated with the Vestal 4-2 Site
that threatened public health have been addressed. EPA summarized the
actions taken at this Site in a Superfund Site Close Out Report dated
September 30, 1998.
EPA and NYSDEC have determined that all appropriate responses under
CERCLA at the Site have been completed, and that no further activities
are necessary. Consequently, EPA is proposing deletion of this Site
from the National Priorities List. Documents supporting this action are
available in the docket.
Dated: July 27, 1999.
Herb Barrack,
Acting Regional Administrator, Region 2.
